The instructions state:
"3. Enter the parent of the $GRAAL directory in the Select root directory field"
Note that it’s the *parent* of $GRAAL you need to select. The Eclipse import wizard will then see all the projects from siblings suites.

We are currently fixing these warnings. You can simply disable the Checkstyle Eclipse plugin until they are fixed. Problems like this with the Checkstyle Eclips plugin is why we removed it as a suggested plugin for Graal development a while ago.

Sorry, there’s not much that can be done that until Truffle changes its Java compliance level.
